The term blue nevus describes a group of skin lesions characterized by dermal proliferation of melanocytes presenting as blue to black nodules on the head, extremities, or buttocks. In most cases, they are acquired and present as a solitary lesion but may also be congenital and appear at multiple sites. Blue nevi are melanotic dermal lesions that commonly presents as a blue nodule on the scalp, extremities, sacrococcygeal region, or buttocks. Its characteristic blue to black hue is frequently confused with other darker pigmented lesions, including malignant melanoma.
